AQA GCSE (9-1) Chemistry for Combined Science: Trilogy Three Year Scheme of Work This 3-Year Scheme of Work offers a flexible approach for KS4 using the combined route through the single Chemistry student book. The suggested timings are based on three lessons per fortnight (assuming a two-week timetable of two lessons one week and one lesson in the other) but can be tailored to suit the needs of a particular class or group of students. Lessons are assumed to be sessions of 40-60 minutes. The teaching scheme is scheduled to finish in the first term of Year 11 to allow time for revision and GCSE examinations in the summer term. Please note that some of these lessons only require partial coverage or are shorter than others and therefore sometimes there are more than three lessons in a fortnight. The maths skills spreads are numbered as the last spread in a chapter but can be used at any appropriate point according to the needs of your students.

The suggested timings are based on three lessons per fortnight (assuming a two-week timetable of two lessons one week and one lesson in the other) but can be tailored to suit the needs of a particular class or group of students. Lessons are assumed to be sessions of 40-60 minutes. The teaching scheme is scheduled to finish in the first term of Year 11 to allow time for revision and GCSE examinations in the summer term. Please note that some of these lessons only require partial coverage or are shorter than others and therefore sometimes there are more than three lessons in a fortnight.
